5. Maintenance to the heat exchanger (CH)
LT.AL.W7H.000.062
• Check the seal between the front plate and the heat
exchanger and the insulation section. Replace sealing.
• Handle the fragile front-plate insulation and the back-plate
insulation of the heat exchanger with great care and do not
let them get wet.
•
Visual inspection of the heat exchanger for scale or dirt. If
you see obvious deposits, than clean the heat exchanger
carefully. Carefully remove any loose dirt with a vacuum
cleaner.
•
Then brush the coils of the heat exchanger (if required a
cleaning brush is available as an accessory) and remove
the loosened particles with a vacuum cleaner.
6. Cleaning plate heat exchanger (DHW) and non return
valve with filter
Scale deposits on the plate heat exchanger cannot be totally
excluded, depending on such variables as tap water quality
and operation mode.
We recommend annual inspections under standard circum-
stances. Please note that following factors may influence the
frequency of inspection:
•
Water hardness
•
Chemical composition of scale deposit
•
Boiler operation hours
•
DHW usage pattern
•
DHW set temperature
